IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 146,088, dated December30, 1873 ;`applieation filed A July 12, 1873.

To all lwhom it may concern.:

Be it known that I, J oEN J AMES MITCHELL, of Hopkinsville, in thecounty of Christian and State of Kentucky, have invented a new andvaluable Improvement in Plows; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawingsmaking a part of this speciiication, and to the letters and iigures ofreference marked thereon.

Figure 1 of the drawings is a representation of my plow in sideelevation, and Fig. 2 is a bottom view of the same. Figs. 3, 4, 5, and 6are detached views of the parts of which my plow is composed.

The nature of my invention consists in the construction land arrangementof a4 plow for use in sandy ground, as will be hereinafter more fullyset forth.

In the accompanying drawings, like letters of reference indicatecorresponding parts.

A represents the foot-piece; B, the share 5 O, the bar or land-'side 5and D, the mold-board.

The foot-pieceA is made of cast-iron, with the front edge curved, asshown. Along the front curved edge is formed the breast a, of the formshown in Figs. l and 3 and projecting toward the mold-board side oftheplow, the two edges of the breast running parallel. At the lower end ofthe foot-piece is a iiange, b, to which the land-side or bar C isattached by bolts; and on the side ofthe foot-piece is a flange, d, towhich the mold-board D is attached also by bolts. The share B may bemade of steel or wrought-iron, and is welded to the land-side or bar C,and further connected with the same by a brace, f, making it verystrong, and at the same time extremely simple. When the land-side andshare are attached to the footpiece A it will be seen that the outeredge of the breast a and the top edge of the share B form nearly, if notquite, a right angle. The mold-board D is made of wood, and has itsfront part made at, or nearly at, a right angle from a' to g/ and y toz, to correspond with the edges of the breast and share. Along these twosides of the mold-board are iianges e e, forming shoulders, so that whenthe mold-board is placed in position said flanges will pass under the`breast and share, while the sides .r y and y z of the mold-board willcome close up to the edges of the breast and share respect-- ively. Themold-board is then firmly bolted to the ilange d.

This construction of the breast and share, with corresponding form ofthe mold-board, brings the mold-board very far forward toward the frontedge, which is of decided advantage, especially in sandy ground, forwhich this plow is more particularly intended.

This plow is cheap and simple, yet strong A and durable, and does itswork in a thorough and superior manner.

What I claim as new, and desire to secure by Letters Patent, is-

l. The foot-piece A, having along the front curvededge the breast a andparallel flange d, and at the lower endthe iiange b, substantially asshown in Fig. 3, and for the purpose speciiied.

2l The combination of the cast-iron footpiece A, having breast a andiianges b d, the share B welded to the `bar O, and the wooden mold-boardD having its front part formed at,

or nearly at, a right angle, all substantially as and for the purposesherein set forth."

In testimony that I claim the above I have hereunto subscribed my nainein the presence of two witnesses.
